Annoying bug in NM1.0.0-8

[Dan Mossor]

Greetings, folks.

I and at least one other individual have noticed an annoying bug with 
NetworkManager-1.0.0-8.fc22.x86_64 but we aren't sure of the root cause 
so we can't legitimately file a BZ on it yet. The issue we're seeing is 
that with a fully updated Fedora 22 Beta system, once NM is in operation 
for a bit it starts to loose connectivity. Not total connectivity, but 
partial. For example, I can run a search on Google for anything and get 
back the usual tens or hundreds of results. but on a single page of 
results I can only successfully open 2 or 3 of them.

Specifically, a few sites I'm noticing I can no longer reach:
https://www.happyassassin.net/
http://docs.kde.org
http://mirrors.rpmfusion.org
http://rsyslog.org

However, all Fedora Project, Red Hat CentOS and GNOME links work just 
fine. Pages from the Stack Exchange family of sites are hit and miss, 
but mostly miss. Also, it is only http traffic - I can hit these sites 
with ftp, ssh or rsync where supported. I have tried using Chrome, 
Firefox, Konquerer, ReKonq, wget and curl and get the same result every 
time. To aid in troubleshooting, I am providing a link to the pcap [0] 
of my wget attempt against the RPM Fusion mirror site - it's 
disappointing, really.

The only commonality I've discovered among the affected systems is that 
they are using Intel wireless adapters. Specifically in my case, a 
Centrino 2230 and a Centrino 2200. The other user I mentioned earlier 
indicated that he believed the fault may lie in the routing tables, but 
I have not confirmed or ruled this out yet - I'm still shooting in the dark.

I know it is not network issues at large, as on this network I have 
other devices - Android, ChromeOS, and Windows 8.1 devices - that all 
work fine. In fact, on one of my affected systems, it was working just 
fine on F21 and NM 0.9.10 before I updated it to F22 last night with 
fedup. This points directly to F22 being at fault, but like I mentioned, 
I don't know if it is NetworkManager or Intel Wireless drivers.

Thoughts? Concerns? Criticisms?

Dan
